10 With that brief background it is appropriate to recite the essential particulars of the offence of which Mr Ritchie has been found guilty.
Those particulars, so far as it is immediately relevant, commence with paragraph (h) of the particulars supplied with the charge:
(h) At all material times in the conduct of cleaning activities in the tank wash facility at the site Owens required its employees to use, or failed to prevent its employees from using, methyl ethyl ketone (MEK) a highly volatile and highly flammable substance, as a cleaning agent.
(i) Owens failed to provide safe system of work for the conduct of tank cleaning activities as part of the business at the site in that:
(i) It failed to ensure that MEK or any other volatile and flammable substance was not used within the confined space of a tank at a temperature above its flash point at a point when potential sources of ignition were brought into or were present in the vicinity of the open hatches of the tank.
(ii) It failed to control the conditions permitting the ignition of MEK or any other volatile or flammable substance at the tank wash bay facility at the site in that it failed to ensure presence of a sufficiently oxygen-depleted atmosphere in the vicinity of MEK or any other volatile flammable substances so as to prevent the risk of ignition.
(iii) It failed to ensure employees were not located above or near the hatch of the tank at the time the tanks were being cleaned.
(j) Owens failed to ensure that plant provided for use by its employees at work was safe and without risk to health in that:
(i) It failed to ensure the tank wash bay facility was earthed so as to prevent the possibility of ignition of MEK or any other volatile or flammable substance used for the purpose of cleaning tanks.
(ii) It failed to ensure that the tank wash bay facility provided means to effect the earthing of tanks present in the said facility so as to prevent the possibility of ignition of MEK or any other volatile and flammable substance used for the purpose of cleaning tanks.
(k) Owens failed to provide adequate information, instruction and training to its employees working in the tank wash bay facility so to ensure their health and safety.
(l) Owens failed to provide such supervision as was necessary to ensure the health and safety of its employees working in the tank wash bay facility.
(m) Owens failed to provide or ensure the use by employees of such footwear as was necessary for the safe performance of work activities involving the use of materials or substances liable to ignition and/or explosion.
(n) As a result of the abovementioned failures employees of Owens including John Howie, Francis James, and John Kaleopa were placed at risk of injury.
11 In these matters, the Court has made a finding that the s 8(1) offence of the Corporation was extensively particularised and amounted to a comprehensive failure by the company to ensure a safe system of work.
In relation to this sentencing exercise, the Court has been provided with affidavits of Mr Nicholson, Miss Woods, and Mr Rose, being affidavits that were before the Court in the previous proceedings. There have been a number of submissions repeated in this sentencing hearing as were put before the Court in the related matters having relevance to this particular matter as they did to the other matters.
